I have a 250 lb turntable assembly that required a Minus K in an old wooden (restored) period Victorian. It was essential to eliminate footfalls. I don't think this could have been done on the cheap. I had a structural engineer look at it before I made the leap. Costly, yes. But necessary in my estimation, given the turntable.
Why spend more than $25 per piece of equipment on vibration reduction?
Do products more expensive than Vibrapods ($24 per set of four) provide superior isolation? I've been pretty happy with the pods, but I wonder whether spending somewhat more, e.g., on Iso-pucks, would bring notably superior results. Or is more a matter of visual, as opposed to audible, aesthetics?
